If you’re looking for a conversation starter, something that will impress each and every person you show it to, this is it! True, many people will scoff at it or ask you what happens when you encounter a TSA agent with this in your pocket, but that’s neither here nor there. It’s the convenience of having a blade with you at all times, even if you forget your EDC knife, and ease of which you can remove the case with the torx bit it comes with that makes this an excellent product. All you have to do is pop out the four corner screws and viola, you’re in business. I’ve had my TactiCall for a little over a month now and after you get used to the added weight, it really becomes a highly useful and functional tool. I was wary at first that the bottle opener would apply too much force to the back side of the phone and could break it, but that’s definitely not the case, ha. The opener is strongly reinforced by the design of the case and it pops the tops off quickly and effectively the first time, every time. The knife comes as sharp as any karambit blade out there and locks up solidly right out of the packaging. The pivot is adjustable if any play develops using the same supplied torx tool as you use to remove the case, so you always have a properly functioning knife. This is a very useful product and does an excellent job protecting your iPhone 5, check it out at www.knifecenter.com.
